The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of two signal conditioners, identified by NSN 7R-6680-011729177-VH, under a presolicitation notice. The requirement is for a limited source, with evaluation criteria based on the lowest price technically acceptable (LPTA), and it necessitates Government Source Approval prior to award. These signal conditioners are critical for measuring liquid and gas flow, liquid level, and mechanical motion, underscoring their importance in defense operations. Interested vendors must submit their proposals along with the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online, and can direct inquiries to Samantha M. Freedman at Samantha.M.Freedman.CIV@us.navy.mil.
